The present document defines the operation of Multimedia Broadcast Multicast Services (MBMS) in support of efficient delivery of IP multicast traffic across the Family SL satellite radio interface. This includes extensions to the Non-Access Stratum (NAS) Layer peer-to-peer interface (defined in ETSI TS 124 007 [1] and ETSI TS 124 008 [2]) between the User Equipment (UE) and a new architectural entity defined as the Broadcast Multicast Service Node (BMSN). In addition, extensions to the IP User Plane Handler (UPH) to interpret IP multicast management and routing protocols are defined in the present document to allow automated triggering of MBMS services as defined for the Family SL satellite radio interface.
